Remove all items from RecyclerView


This works great for me:

public void clear() {    int size = data.size();    if (size > 0) {        for (int i = 0; i < size; i++) {            data.remove(0);        }        notifyItemRangeRemoved(0, size);    }}

or:

public void clear() {    int size = data.size();    data.clear();    notifyItemRangeRemoved(0, size);}

For you:

@Overrideprotected void onRestart() {    super.onRestart();    // first clear the recycler view so items are not populated twice    recyclerAdapter.clear();    // then reload the data    PostCall doPostCall = new PostCall(); // my AsyncTask...     doPostCall.execute();}


Avoid deleting your items in a for loop and calling notifyDataSetChanged in every iteration. Instead just call the clear method in your list myList.clear(); and then notify your adapter

public void clearData() {    myList.clear(); // clear list    mAdapter.notifyDataSetChanged(); // let your adapter know about the changes and reload view.}


setAdapter(null);

Useful if RecycleView have different views type
